   • Culture and delivery discussion (30 min)

Our Philosophy:
We value principles over buzzwords and pragmatic solutions over perfection. We believe in meaningful in-person collaboration paired with the autonomy to do your best work—wherever you are.

Let’s build something meaningful together.
If you’ve lived the difference between engineering theory and practice, can deliver design and build projects with minimal supervision, and know when to refine vs. when to ship—we want to talk to you.

Here at Atheneum, diversity and inclusion is not just part of our culture, it is ingrained in our DNA. We do not discriminate in any way when assessing applications.
